Koreanska Gentle Monster skapar glasögon som små konstverk. Senaste släppet heter 13 och syftar på 13:e månaden Undecember. "Gentle Monster’s ‘13’ Campaign sets place in a world where the moon shifts out of place and axis, slowly floating away from Earth creating the 13th month, Undecember. Animals start to act differently and people develop a dependency on either religion or technology. The changes in climate spark a split between anxiety and hope. Gentle Monster illustrates a message of hope brought from the insight and imagination spawned from the new world."
